When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand.
The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
The muscle is the diaphram and it is located just beneath your lungs.
The action is the flattening of your diaphragm, or the muscle that helps your lungs inhale and exhale.

diaphragm
The diaphragm is a muscle located below the lungs that contracts and moves downward when you inhale, creating more space for your lungs to expand. This allows for air to be drawn into the lungs for oxygen exchange. When you exhale, the diaphragm relaxes and moves back up, pushing air out of the lungs.
The diaphragm is a muscle located below the lungs that plays a crucial role in the process of breathing. It contracts and flattens when you inhale, creating a vacuum to draw air into the lungs, and relaxes when you exhale, allowing air to be pushed out.
Simple answer. All your life your lungs inhale and exhale oxygen. This is facilitated by the diaphragm, a muscle just below the lungs. When this muscle moves down a partial vacuum is created allowing the lungs to inflate filling the space created by the moving diaphragm, it then moves up again compressing the lungs and therefore expelling the air in them.
The diaphragm of the lung is the muscle below the lungs that stretches the lungs, helping them expand when you inhale. When you exhale, it helps push air up out of the lungs.
It allows the lungs to expand when you inhale and they shrink when you exhale.
the lungs recoil/contract to push air out using its smooth muscle
when lungs inhale oxygen what doesit exhale as waste
